Simplified procedures pioneered by Seed and Idriss have been widely accepted and used in practice for assessing cyclic liquefaction resistance and potential of sandy soils. Extension of the simplified procedures to assessing liquefaction resistance of fine-grained soils has not achieved the same degree of success. Ku and Juang proposed a piezocone test (CPTu)-based CRR model that is applicable to both sand-like and clay-like soils. In this paper, this CPTu-based CRR model is used to assess the liquefaction susceptibility of the clay-like soils. The results show that for the most part, the proposed CRR model is quite consistent with the criteria proposed by Bray and Sancio (2006).
